Sony’s ‘secret’ information, the ones sensitive to the company are at stake with the hacking incident. The techniques used by the hackers could have even cracked the best of the best antivirus software. “This incident appears to have been conducted using techniques that went undetected by industry standard antivirus software,” the FBI said in a statement released Saturday.

The teams, which are working on revealing the source of the attack, have affirmed that the malware was totally unique and hence undetectable by the industry of antivirus makers.

The hackers call themselves ‘’Guardians of Peace’’(GOP).”This is a game-changer for us in the United States, this level of maliciousness is unprecedented. I’ve never seen it, ever,” said Jim Penrose, a former National Security Agency computer security expert.

On Friday, the hackers sent another mail to all Sony employees, which stated that the act was just a very small part of their future plans. It further warned Sony employees stating, “make your company behave wisely.” If they did not, “not only you but your family will be in danger.” Some employees were even told to shut off mobile phones and tablets, though some could still check e-mail. Kevin Mandia, CEO of Mandiant, the security firm said, “this was an unparalleled and well planned crime, carried out by an organized group, for which neither SPE nor other companies could have been fully prepared.”

The country of origin of the GOP still remains unknown, nor has Sony revealed some of the threat messages they’ve been sending. The security teams are speculating that the hackers might possibly be from North Korea, however North Korea has denied having a role in the hack. It has been two weeks to the ongoing cyber attack now. Sony is one of the hardest hit in any cyber attack, there have been assaults in the past on some of the big names in U.S. including Target, P.F. Chang’s, The Home Depot, Goodwill, Dairy Queen, JPMorgan Chase and the U.S. Postal Service.
